从 JDBC、Java 调用 Sqlserver 存储过程

Question

我可以从 toad sql server 运行这个查询。

exec msp_FormBsBa_yeni 0,'20150101','20150131',5000,0,2,0,null,1,null,0

从我在 java 中的应用程序中，由于语句没有返回结果集，它产生了错误。我尝试了很多事情，但我无法解决它。感谢您的帮助。

    // Connection,Resultset ve PrepStatement Declaration
    Connection connection = null;
    PreparedStatement pstmt = null;
    ResultSet rsa = null;
    List<EntCari> listrows = new ArrayList<EntCari>();

    try {
        connection = ConnectionFactory.getConnection();

        CallableStatement callableStatement = connection
                .prepareCall("{call msp_FormBsBa_yeni(0,N'20150101',N'20150131',5000,0,2,0,null,1,null,0)}");

        rsa = callableStatement.executeQuery();

        // 2:resultset check
        if (!rsa.next()) {
            System.out.println("no data");
        } else {
            do {
                // System.out.println("data exists");
                // Statements
                EntCari row = new EntCari();
                row.setMusteriadi(rsa.getString("Unvan"));// rsa.getxxx("column")
                listrows.add(row);

            } while (rsa.next());
        }

        // 2---

    } catch (SQLException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    } finally {
        DbUtil.close(rsa);
        DbUtil.close(pstmt);
        DbUtil.close(connection);
    }

toad sql server 的结果如下所示。

存储过程如下（sp的一部分，很长）

Answer 1

您不能在返回游标/ResultSet 的 Transact-SQL CallableStatement 上调用 executeQuery()。调用该过程的正确方法是：

// You should really use bind variables here...
CallableStatement call = connection
    .prepareCall("{call msp_FormBsBa_yeni(?, ?, ?, ...)}");
call.setInt(1, ...);
call.setString(2, ...);

// This returns true if there are any remaining ResultSets to fetch
if (call.execute()) {
    do {
        try (ResultSet rs = call.getResultSet()) {
            // Consume the result set here...
        }
    }

    // Move on to the next result set, if any
    while (call.getMoreResults());
}

如果您想要完全通用，您还必须检查Statement.getUpdateCount()，以防更新计数与您的过程中的结果集交织在一起。

Answer 2

当我在数据库客户端（例如 SQL Server Management Studio）中执行查询时，会返回一个表。

我的存储过程很长，有一些插入和更新语句。如果存储过程在最终选择之前执行任何插入或更新，则 JDBC（SQL Server 驱动程序）会与行数混淆（并且将引发语句未返回结果集的异常）。幸运的是，修复非常简单：我只需要在存储过程的开头添加 SET NOCOUNT ON 即可。所以我的代码看起来像：

CREATE PROCEDURE dbo.msp_FormBsBa_yeni
@vFirmaNo as integer,
@IlkTarih as datetime,
@SonTarih as datetime,
@MinTutar as float,
@Bs_Ba_tip as bit,
@BirlestimeTuru as tinyint,
@SonradanMuhasebelesenSeriDahilEdilmesin_fl as bit,
@SonradanMuhasebelesenSeriStr nvarchar(MAX),
@Aylik_BsBa_fl as bit,
@PerakendeCariKodu AS nvarchar(25),
@EvrakDetayliRapor_fl as bit
AS
BEGIN
  SET NOCOUNT ON

非常感谢您的贡献

这里有两种方法可以实现..

String SPsql = "EXEC msp_FormBsBa_yeni ?,?,?";   // for stored proc taking 3 params
Connection con = SmartPoolFactory.getConnection();   
PreparedStatement ps = con.prepareStatement(SPsql);
ps.setEscapeProcessing(true);
ps.setQueryTimeout(<timeout value>);
ps.setString(1, "val");
ps.setString(2, "val";
ps.setString(3, "val");
ResultSet rs = ps.executeQuery();

或使用 JDBC scape 语法

CallableStatement cStmt = conn.prepareCall("{call msp_FormBsBa_yeni (?, ?, ?) }");
cStmt.setString(1, "val");
cStmt.setString(2, "val");
cStmt.setString(3, "val");
cStmt.registerOutParameter(4, Types.INTEGER); // register the output params 
cStmt.registerOutParameter("inOutParam", Types.INTEGER); // or by param name
